Original Abstract Submitted
A comparison circuit and an image sensing device including the same are disclosed. The comparison circuit includes a comparison block configured to include a comparator that compares signals of input nodes with each other within a first period and outputs a signal corresponding to a result of the comparison to an output node and configured to initialize the comparator by allowing a voltage of the output node to be fed back to an input terminal of the comparator within a second period, and a stabilization circuit configured to supply a first voltage to the output node within the second period. In the second period, the stabilization circuit is connected to the output node to supply the first voltage. In the first period, connection between the stabilization circuit and the output node is cut off.
